Ultrasonic probe

Abstract

The present disclosure relates to an ultrasonic probe used in a medical instrument for ultrasonic diagnosis, and the ultrasonic probe includes a strain relief having a structure for preventing a cable from being damaged by twisting or sharp bending.

1 . An ultrasonic probe comprising:
 a case to accommodate an ultrasonic transceiver;   a cable to connect the ultrasonic transceiver and a main body of a medical instrument; and   a strain relief provided outside the case to prevent breakage of the cable,   wherein the strain relief is formed in a truncated conical shape and includes a passage through which the cable is capable of passing, and   the strain relief includes portions having at least two truncated conical shapes divided perpendicular to a central axis of the strain relief.   
     
     
         2 . The ultrasonic probe according to  claim 1 ,
 wherein two adjacent portions among the portions having the at least two truncated conical shapes of the strain relief are rotatable with respect to each other at a predetermined angle.   
     
     
         3 . The ultrasonic probe according to  claim 1 ,
 wherein a portion having a fixed end of the strain relief among the portions having the at least two truncated conical shapes of the strain relief is rotatable with respect to the case at a predetermined angle.   
     
     
         4 . The ultrasonic probe according to  claim 2 ,
 wherein when a free end of the strain relief is rotated by more than the predetermined angle, a torsional force is first applied to a portion adjacent to the free end among the two adjacent portions, and a torsional force is later applied to a portion adjacent to a fixed end of the strain relief among the two adjacent portions.   
     
     
         5 . The ultrasonic probe according to  claim 1 ,
 wherein when a free end of the strain relief is rotated, a torsional force is first applied to a portion adjacent to the free end among the portions having the at least two truncated conical shapes, and a torsional force is later applied to a portion adjacent to a fixed end of the strain relief.   
     
     
         6 . The ultrasonic probe according to  claim 1 ,
 wherein the passage is provided asymmetrically inside the strain relief so that the strain relief is capable of being bent to one side.   
     
     
         7 . The ultrasonic probe according to  claim 6 ,
 wherein an end of the passage on a fixed end side of the strain relief is provided to deviate from a center of the strain relief.   
     
     
         8 . The ultrasonic probe according to  claim 6 ,
 wherein the passage is provided such that a central axis of the passage is spaced from a central axis of the strain relief by a certain distance.   
     
     
         9 . The ultrasonic probe according to  claim 1 ,
 wherein the passage includes a plurality of recesses provided on a side wall of the passage so that the strain relief is bent in multiple steps.   
     
     
         10 . The ultrasonic probe according to  claim 1 ,
 wherein the strain relief includes a reinforcing member provided at one side of the passage so that the strain relief is capable of being bent to one side.   
     
     
         11 . An ultrasonic probe comprising:
 a case to accommodate an ultrasonic transceiver;   a cable to connect the ultrasonic transceiver and a main body of a medical instrument; and   a strain relief provided outside the case to prevent breakage of the cable,   wherein the strain relief includes a passage through which the cable is capable of passing, and a reinforcing member provided at one side of the passage so that the strain relief is capable of being bent to one side.   
     
     
         12 . The ultrasonic probe according to  claim 11 ,
 wherein the strain relief is formed in a truncated conical shape, and   the strain relief includes portions having at least two truncated conical shapes divided perpendicular to a central axis of the strain relief.   
     
     
         13 . The ultrasonic probe according to  claim 12 ,
 wherein two adjacent portions among the portions having the at least two truncated conical shapes of the strain relief are rotatable with respect to each other at a predetermined angle.   
     
     
         14 . The ultrasonic probe according to  claim 12 ,
 wherein a portion having a fixed end of the strain relief among the portions having the at least two truncated conical shapes of the strain relief is rotatable with respect to the case at a predetermined angle.   
     
     
         15 . The ultrasonic probe according to  claim 13 ,
 wherein when a free end of the strain relief is rotated by more than the predetermined angle, a torsional force is first applied to a portion adjacent to the free end among the two adjacent portions, and a torsional force is later applied to a portion adjacent to a fixed end of the strain relief among the two adjacent portions.
